TELEWAVE MODEL 44 SERIES BROADBAND RF WATTMETERS

• The Telewave Model 44 series RF Wattmeters are compact, versatile instruments used for direct measurement of forward and reflected RF power. Thanks to their wide band capability and dynamic range, no elements, inserts, or bandswitching is required.
• The 20uA taut-band meter is shock mounted in a rugged, diecast housing, making these instruments ideal for mobile radio installation in aircraft or vehicles, as well as base stations.
• Models with a -P suffix include an RF sampling port, with an output 40dB below the transmission line level, for frequency measurement or spectral analysis. This input and output port is accessed via a
• BNC connector located on the side of the units. It allows for injecting an input signal into the unit under test or can be used for spectrum analysis and frequency measurements without affecting the operation of the meter.
• Five power scales are provided, The 500 watt scale will test most high powered transmitters, while the 5 watt scale makes it simple to tune low powered portables. The excellent stability of these and the ability to switch them from one power range to another to check the calibration eliminated the need for a secondary standard to check calibration

TELEWAVE LOW POWER COAXIAL RF TERMINATIONS

• Telewave offers a full selection of coaxial loads with extremely low VSWR. Applications include hybrids, isolators power monitors, wattmeters, and coaxial line terminations.
• All loads are built ruggedly to withstand bench or field use. Power rating provides substantial overload protection.
• Unlike liquid dielectric loads, these dry dielectric loads can be operated in any position.
• Connectors have Silver Plated centre pins for optimum conductivity. (Excluding the TWL-01 which has a Gold Plated centre pin)

FEATURES

• Extremely Low VSWR
• CW Power Ratings to 75 W
• Broad Frequency Range
• Rugged Construction
• Type N or UHF connectors

TELEWAVE COAXIAL RF TERMINATIONS (50 TO 150 WATTS)

• Telewave coaxial loads feature extremely low VSWR. Applications include hybrids, isolators, power monitors, wattmeters, and coaxial line terminations.
• Telewave loads are custom machined to withstand bench or field use. The conservative power rating provides substantial overload protection. Unlike liquid dielectric loads, these dry dielectric loads can be operated in any position.
• All connectors have gold-plated centre pins for optimum conductivity. Quick-change connectors are standard on Telewave loads from 50 Watts and up, except TWL-60. Specify connector type(s) when ordering.
• The TWL-150 Bench Load is ideal as a general purpose termination. It is perfectly suited for terminating the Model 44 Series Broadband Wattmeters, or any other application requiring a very low VSWR, 50 Ohm termination.
• For added flexibility, straight or elbow-type male-male adaptors are available.

FEATURES

• Extremely Low VSWR
• CW Power Ratings to 150 Watts
• Dry Dielectric
• Broad Frequency Range
• Rugged Construction
• Type N or UHF, M/F connectors
